Medium frequency energy supply for rail vehicles

摘要

The subject matter of the present invention is an electronic circuit for the bidirectional conversion of a high input voltage to a direct-current output voltage with indirect coupling, more specifically for use in a power supply system for rail vehicles, that is provided with a primary converter (4), one single common transformer (5) and a secondary converter (6), the primary converter (4) being composed of at least three primary converter sections (4.1 - 4.n) connected in series, the output lines of which are each connected to a respective one of the transformer primary windings (5.1 - 5.n).
